The cells of an embryo get their roles when they are capable of differentiating autonomously in a neutral environment such as a petri dish or test tube. (the environment is neutral with respect to the development pathway.) This process of giving different roles to embryonic cells is called Cell Specification. Continue reading How do cells in Embryo get their Roles to Play?

Spores and Zygote are examples of totipotent cells. Continue reading What is meant by Cellular Totipotency?
